MongoDB Drop Database

Last Updated: 30 May, 2023

To drop a MongoDB database, we can use the dropDatabase() method.

To drop a database, we need to follow the given steps:

1. Open the MongoDB shell by running the mongo command in our terminal or command prompt.

2. Switch to the database that we want to drop using the use command.
   For example, if we want to drop a database named "schoolDB", run the following command:

    use schoolDB
   

3. Once we have switched to the desired database, we can issue the dropDatabase() command to drop it:

    db.dropDatabase()
   

   This command will delete the current database we're connected to (in this case, "schoolDB") and remove all its collections and data.

4. After executing the dropDatabase() command, MongoDB will return a JSON object with the result of the operation. If the database was dropped successfully, we'll see the following output:

    { "dropped": "schoolDB", "ok": 1 }
   

Please exercise caution when using the dropDatabase() command, as it permanently deletes the entire database and its data. Make sure we have a backup or that we genuinely want to remove all data associated with the database.
